<p>
    RGraph.Text() is a text drawing function that allows vertical and horizontal alignment, and allows you to specify the angle of the
    text too. The animation is done by a simple gobal variable, setTimeout() and redrawing the entire
    canvas every frame. Perhaps not the most efficient of methods, but remember that your Javascript will likely be
    running on computers that have more processing power than
    some small countries... <a href="javascript: location.href = location.href">Reset the page</a>
</p>

<p>
    In a similar vein you could easily make some text that bounces from one side of the screen to the other,
    hurrah - the return of &lt;marquee&gt;!

        reference to the Text() function can be found in the <a href="../docs/api.html#functions.other">API docs</a>.
